Just as you can buy almost anything on eBay, you can sell almost anything, too. Using a simple listing process, you can put all of the junk in your basement up for sale to the highest bidder. When you sell an item on eBay,you pay listing fees and turn over a percentage of the final sale price to eBay.
Once you register with eBay, you can access all of your eBay buying and selling activities in a single location called My eBay.
eBay Infrastructure
A series of service disruptions in 1999 caused real problems for eBays business. Over the course of three days, overloaded servers intermittently shut down, meaning users couldnt check auctions, place bids or complete transactions during that period. Buyers, sellers and eBay were very unhappy, and a complete restructuring of eBays technological architecture Followed.
In 1999, eBay was one massive database server and a few separate systems running the search function. In 2005, eBay is about 200 database servers and 20 search servers.
The architecture is a type of grid computing that allows for both error correction and growth. With the exception of the search function, everything about eBay can actually run on approximately 50 servers-Web servers,application servers and data-storage systems. Each server has between 6 and 12 microprocessors. These 50 0r so servers run separately, but they talk to each other,so everybody knows if there is a problem somewhere. eBay can simply add servers to the grid as the need arises.
